TROUBLE DIAGNOSIS

Ambient Sensor CircuitBJS000GC
COMPONENT DESCRIPTION
Ambient Sensor
The ambient sensor is attached on the hood lock stay. It detects
ambient temperature and converts it into a resistance value which is
then input into the unified meter and A/C amp.
AMBIENT TEMPERATURE INPUT PROCESS
The unified meter and A/C amp. includes a processing circuit for the ambient sensor input. However, when the
temperature detected by the ambient sensor increases quickly, the processing circuit retards the unified meter
and A/C amp. function. It only allows the unified meter and A/C amp. to recognize an ambient temperature
increase of 0.33°C (0.6°F) per 100 seconds.
As an example, consider stopping for a few minutes after high speed driving. Although the actual ambient tem-
perature has not changed, the temperature detected by the ambient sensor will increase. This is because the
heat from the engine compartment can radiate to the front grille area, location of the ambient sensor.
DIAGNOSIS PROCEDURE FOR AMBIENT SENSOR
SYMPTOM: Ambient sensor circuit is open or shorted. (21 or − 21 is
indicated on unified meter and A/C amp. as a result of performing
self-diagnosis STEP-2.)
1. CHECK VOLTAGE BETWEEN AMBIENT SENSOR AND GROUND
1. Disconnect ambient sensor connector.
2. Turn ignition switch ON.
3. Check voltage between ambient sensor harness connector
E257 terminal 1 and ground.

Fitting AdjustmentBIS000VP
LONGITUDINAL AND LATERAL CLEARANCE ADJUSTMENT
1. Remove hood lock, loosen the hood hinge nuts and close the hood.
2. Adjust the lateral and longitudinal clearance, and open the hood to tighten the mounting bolts to the spec-
ified torque.
3. Install the hood lock temporarily, and align the hood striker and lock so that the centers of striker and lock
become vertical viewed from the front, by moving the hood lock laterally.
4. Tighten hood lock mounting bolts to the specified torque.
FRONT END HEIGHT ADJUSTMENT
1. Remove the hood lock and adjust the height by rotating the bumper rubber until the hood becomes 1 to1.5
mm (0.04 to 0.059 in) lower than the fender.
2. Temporarily tighten the hood lock, and position it by engaging it with the hood striker. Check the lock and
striker for looseness, and tighten the hood lock mounting bolts to the specified torque.
CAUTION:
Adjust right/left clearance between hood and each part to the following specification.
1. Hood hinge 2. Nut 3. Hood stay
4. Hood lock 5. Bolt

HOOD

SURFACE HEIGHT ADJUSTMENT
1. Remove hood lock, and adjust the surface height difference of hood, fender and headlamp according to
the fitting standard dimension, by rotating RH and LH bumper rubbers.
2. Install hood lock temporarily, and move hood lock laterally until the centers of striker and lock become ver-
tical when viewed from the front.
3. Check that the hood lock secondary latch is properly engaged
with the secondary striker with hood's own weight.
4. Check that the hood lock primary latch is securely engaged with
the hood striker with hood's own weight by dropping hood from
approx. 200 mm (7.87) height.
CAUTION:
Do not drop hood from a height of 300 mm (11.81 in) or
more.
5. Move hood lockup and down until striker smoothly engages the
lock when the hood is closed.
6. When pulling the hood opener lever gently, make sure that front
end of the hood rises by approximately 20 mm (0.79) and that hood striker and hood lock primary latch is
disengaged. Also make sure that hood opener returns to the original position.
7. After adjustment, tighten lock bolts to the specified torque.

REMOVAL
Hood Assembly
1. Support the hood striker with a proper material to prevent it from
falling.
WARNING:
Body injury may occur if no supporting rod is holding the
hood open when removing the hood stay.
2. Disconnect washer hose at the connecting point.
3. Remove the hood stays from the stud balls on the body side.
4. Remove hinge nuts on hood and remove hood assembly.
CAUTION:
Operate with two workers, because of its heavy weight.
INSTALLATION

Install in the reverse order of removal.

Apply Anti-Corrosion or equivalent to the attaching portion of hood hinge, hood ledge, and hood assembly.

After installing, perform hood fitting adjustment. Refer to BL-13, "Fitting Adjustment" .

Removal and Installation of Hood Lock ControlBIS000VR
REMOVAL
Hood Lock and Hood Lock Cable
1. Remove hood lock bolts.
2. Disconnect hood lock cable from hood lock.
3. Remove fender protector (LH). Refer to EI-23, "
FENDER PRO-
TECTOR" .
4. Remove hood lock cable clips, from radiator core upper support
and hood ledge.
5. Remove hood opener and grommet on lower dashboard.
6. Pull out hood lock cable toward passenger room.
CAUTION:
While pulling the cable, be careful not to damage (peel) outer surface of the cable on edges of
